My local supermarket ONLY uses self-serve checkouts save for about 3 that are staffed. When I started smoking a few months ago I had a freak-out moment (thinking that everything isn't real isn't nice, bro) and decided I should go to the shops to buy some food. Stood in the queue for five minutes before realising I was at the front and people had been staring at me for ages. Meanwhile, I'd forgotten I was in the supermarket at all. Embarrassing as shit.
